Different pathways of the eye

I remembered when we talked about people who have spastic paralysis and cannot consciously control their arm which is stuck in antigravity positions, but when a ball is thrown at them, they can block the ball out of instinct. There has to be a pathway between the the visual system, and the unconscious part of the brain that is in control independent of the "I" function. Can we scan the brain of these people as they are blocking the object out of instinct to locate this pathway?

Also on another note, there is something special about making eye contact with someone else. There is a big difference if someone is talking to you and looking into your eyes, vs. not looking into your eyes. There is a deeper connection, like the connection of two "I" functions recognizing  each other and communicating directly with each other. The eye is a gateway that allows this to happen. Why is there something special about this sense of making eye contact. I looked up studies on PubMed and found much research that shows there are EEG correlates with eye contact and how far away a person is

Also research has shown that maintaining eye contact for longer makes a person feel like they are being judged more positively. http://cat.inist.fr/?aModele=afficheN&cpsidt=3626497

Where in the visual pathway is the picture in the head being evaluated on these criteria? Were is this pathway? What about being with damage to the visual cortex, people who are blind, are they able to compensate for these feelings vital to everyday social interactions?
